Alexander Markov 3f717df415 [vm/compiler] Infer array element type from static type Iterable<E> ...

Inferring array element type E from static type Iterable<E> allows
compiler to remove extra checks left from iterator code.
This is valid as List<E> implements Iterable<E>.

This change makes for-in loops over built-in lists with static types
Iterable<E> as efficient as loops over List<E>.
